It's expected that this message shows up N
times for ScipyDifferentialEvolutionOptimizer(..., workers=N)
, because the objective is pickled there for each worker. Wouldn't consider that a bug.
The messages appear far greater than N
times, e.g. using the problem from #881 and the following script.
import pypesto.petab
import pypesto.optimize
petab_yaml = 'icg_sd.yaml'
pypesto_importer = pypesto.petab.PetabImporter.from_yaml(petab_yaml)
pypesto_problem = pypesto_importer.create_problem()
optimizer = pypesto.optimize.ScipyDifferentialEvolutionOptimizer(
options={
'strategy': 'best1bin',
'maxiter': 8000,
'mutation': (0.2, 1),
'recombination': 0.7,
'popsize': 70,
'init': 'latinhypercube',
'polish': True,
'workers': 8,
}
)
result = pypesto.optimize.minimize(
pypesto_problem,
optimizer=optimizer,
n_starts=4,
filename=None,
)
Okay, potentially multiplied by popsize
or maxiter
:see_no_evil: .
The best we can do is not showing the message during unpickling. The rest is on scipy.
Moved "using existing" message to debug level in #912, should reduce appearance unless in debug mode.
Bug description Many of these messages in the log file, possibly every function evaluation during optimization.
Expected behavior Only one of these messages.
To reproduce Run the example in #881
Replacing the optimizer with
pypesto.optimize.ScipyOptimizer()
results in the expected behavior.Environment
